And just like that, Zverev steps up a gear with two strong serves to force two errors. 30-30.

And still the supporters on Philippe Chatrier roar as Molcan wins a drop shot at the net before Zverev fires a backhand wide to fall 0-30 behind.

Alex Molcan can't help but smile as Philippe Chatrier stands up in support after he sneaks a hold.

He's on the board in the third set and celebrates by lifting both hands into the air.

The crowd have a new cult hero.

It just feels right now like that it’s a bit of target practice for Alexander Zverev. The last couple of forehands he’s hit have been huge and he’s had all sorts of times to produce these shots.

A very encouraging service game for Arthur Rinderknech as he holds to love.

That's just a reminder to Taylor Fritz that he may be on top but there is still a long way to go in this match.

If Rinderknech can find his first set form, he'll bring the crowd with him and then who knows where this match might end up?

Alex Molcan's in a battle with himself now. He fires in two more errors as Zverev wins his latest service game to 15.

Molcan's only won four of the last 27 points.

Almost cruel cheers for Alex Molcan from the fans on Philippe Chatrier as the Slovakian finally wins a point on Alexander Zverev's serve.

The German's soon level again though with a thunderous forehand winner down the line.

Molcan saves the first but can't do anything in the next rally as Zverev wins again at the net. The German's a double-break up in the third set.

We've played one hour and 28 minutes so far. Those that were with me for Djokovic's match with Fucsovic last night will know that was just about the length of their first set.

Two completely different matches.

He's making it look so easy out there.

Alexander Zverev backs up his break with yet another hold to love. He's won the last 11 points on his serve.

It's happened again. Alex Molcan errors to hand Alexander Zverev a cheap break at the start of a set.

If it wasn't already, it's a very long road back now for the Slovakian.

Molcan drops to a slouch, shaking his head after he nets to set up two break points.

We've already had one epic on Court Suzanne Lenglen today and the way Arthur Rinderknech started, it looked like we might be on for another.

However, he is really having to battle now and Taylor Fritz is turning the screw.

Down 15-40, Rinderknech pulls out two big serves to get to deuce but then hands the advantage to his American opponent with a double fault.

Fritz gobbles up the chance at the third time of asking before holding with ease. Rinderknech needs to try and find the energy that he showed in the first set.

Alex Molcan just wants this match over now I feel. He drives a backhand wide to slip to 15-30 at the start of this third set.

Yet another love-hold for Alexander Zverev as he finishes off the second set by forcing an error from Alex Molcan.

Molcan's never won a match from two sets down. I suspect that won't be changing tonight.

Another winner and Alex Molcan must be wondering what he can do to fix this. 40-0. Three set points.

Zverev's in a hurry tonight. Two strong serves sees him race to 30-0.

On the lack of women playing in the night session matches:

If this tournament cares about treating women and women’s tennis equally with men’s tennis, it will find a way and stop making excuses.

If you’re just going to play best of three in the evening, play two women’s matches back to back or play a women’s match and a doubles match. There are ways around this if you care enough. They don’t care enough.
